High-resolution HST images with WF/PC and WFPC2 have allowed the morphological classification of faint field galaxies to ZSM ~ 24.25 mag (Bj ~ 26.0). We find that the differential galaxy counts at these faint magnitudes are dominated by late-type spiral/Irregular galaxies. The elliptical and early-type spirals remain roughly consistent with the no-evolution predictions for these types, and firmly place the epoch of giant galaxy formation to beyond z ~ 0.8. Close examination of the late-type spiral/Irregular population supports a picture in which recent star-formation has occurred in a significant fraction (35 %) of this population, and that the remainder are lower redshift objects under-represented in the local surveys.
